Inventor: SCHWARTZ NIRA
IPC: G06T7/00
Filed: 1994-11-09
Abstract: Fast image acquisition and image process control are used to advantage to measure dynamic and transient phenomena. This technique distinguishes fluid from bubbles by taking an image of a container containing fluid and modifying the gray levels of the image. Unmodified image processing can be performed without the disadvantage of large time consumption. The technique is used for detecting fluid levels and bubble, by counting image pixels dedicated to bubbles or to fluid along vertical or horizontal lines within the image. The rate of change of liquid level and the amount of bubbles with time indicate leakage in containers while they are in a dynamic state. The inspection of transient phenomena during a dynamic state gives an indication of the final quality and quantity of a product inside a container. It also provides feedback for the determination of fill nozzle operation, with the advantage of easy calibration and adjustment for the right amount of bubbles within the container. It also provides an indication of mechanical or thermal failures and feedback to indicate any unit which deviates from preset parameters. The system is highly beneficial in the beer and soft drink industry where the taste of the product is highly influenced by the amount of bubbles within the container.

IPC: B25D17/06
Filed: 1993-05-12
Abstract: A drilling arrangement is provided having a reciprocating piston hammer which hammers a drill bit for hydraulic down-the-hole piston hammer drilling. The drilling arrangement uses a liquid for driving the reciprocating piston hammer with respective impacting facing surfaces between the hammer and the drill. The respective impacting facing surfaces are formed such that at the moment of impact some of the liquid is forced between the impacting surfaces. This substantially reduces if not eliminating altogether the cavitation which might otherwise develop.

Title: Automatic Instant Lighting System for Liquid Fuel Burner
Inventor: LONG NORRIS R
IPC: F23C5/02
Filed: 1995-02-10
Abstract: A fuel control mechanism for a liquid fuel burner includes a fuel regulating valve which is responsive to flow of liquid fuel through a fuel feed tube for movement between a starting position and a running position.  When a fuel control valve for the burner is opened, flow of liquid fuel through the fuel feed tube moves the fuel regulating valve to a starting position in which the fuel regulating valve restricts flow of fuel through a fuel inlet.  Air is thereby drawn through an air inlet and mixes with the fuel.  After the burner is started and liquid fuel is vaporized within the generator, flow of fuel through the fuel feed tube slows, and the fuel regulating valve falls by virtue of its weight to the running position in which the fuel regulating valve does not restrict flow of fuel through the fuel inlet.  Air flow through the air inlet is thereby discontinued, and only liquid fuel flows through the fuel feed tube.

Title: Multiple capacitor transducer
Inventor: DELATORRE LEROY C
IPC: G01L9/00
Filed: 1995-03-30
Abstract: ABSTRACT         The present invention relates to pressure and torque transducers using relatively small capacitors and micro displacements for use in high pressure transducers requiring a wide pressure range of operations under changing temperature conditions and for producing measurements with great accuracy.          In the present invention, four capacitors are defined by spaced apart capacitor plates respectively located on spaced apart capacitor base members.  The capacitor base members are vertically arranged in a housing.  The capacitor plates for each capacitor are disposed at equally offset locations relative to a central vertical axis for the device so that two capacitors are located on either side of the vertical axis.          One of the capacitor base members has a movable section which can be angularly torques or displaced about a vertical torque axis by an applied torque force to dependently vary the respective capacitance of two of the capacitors, herein referred to as "measurement capacitors".  The angular torque is obtained by a spirally wound bourdon tube which, when subjected to internal fluid pressure, produces a torque about the torque axis.  The torque axis is centrally located in the angularly displaceable capacitor base member.  The other two capacitors are fixed spacially with respect to one another on the base members and are herein referred to as "reference capacitors".          By arranging the capacitor base members of the measurement capacitors so that related capacitance between capacitor plates on the base member are varied as a function of an angular relationship of the capacitor plates relative to a mid-plane, a high capacitance sensitivity can be obtained with low angular torque deflection.

Title: Note or note pad preparation method
Inventor: MERTENS TOMOTHY A
IPC: B42D5/00
Filed: 1993-10-07
Abstract: A method for making custom printed notes or note pads (10). One or more sheet assemblies (10) are provided which have first and second sheets (12, 13) and a pattern of pressure-sensitive adhesive (16) on the rear major surface (15) of each of the sheets that contacts and is releasably adhered to the rear major surface (15) of the other sheet only in nonadhesive areas. Indicia is printed on the front major surfaces (14) of the sheets using a conventional copy machine (19). The sheets can then either be cut along predetermined lines to form the custom printed notes (10), or the sheets of a plurality of such printed sheet assemblies can be separated, stacked to adhere the patterns of pressure-sensitive adhesive (16) on the rear major surfaces (15) of the sheets to the front major surfaces (14) of the sheets with the edges of the sheets in a predetermined orientation with respect to each other; and the stacked sheets can be cut along predeterrnined lines to form custom printed note pads (10). Assemblies and tablets are de-scribed. Each assembly consists of two sheets. Each sheet bears a pattern of pressure-sensitive adhesive (16) on one major surface (15). The pattern contacts the adhesive-bearing surface of the adjacent sheet only in nonadhesive areas. The pressure-sensitive and nonadhesive areas are so prepared that each sheet can be cleanly peeled from the adjacent sheet, even after prolonged sto-rage. When a single ply is used, it may be formed into a folded configuration, each section on either side of the fold forms a sheet. The sheets may be separated and formed into stacks. The nonadhesive face of each sheet may be treated with a release material so each sheet in the stack may cleanly peel from the underlying sheet.

Title: Colloids to increase coefficient of friction in carbonless paper pad coatings
Inventor: KRAFT KEITH A
IPC: B41M5/124
Filed: 1993-11-30
Abstract: A composition suitable for use as a pad-coat or release coating for carbonless paper constructions, the composition containing about a) 0.1-10.0 weight percent inorganic colloid having a particle size in the range of about 1-125 nm; b) 0.1-5.0 weight percent abherent material; c) 60.0-99.9 weight percent water, and d) 0-25 weight percent binder, based upon the total weight of the coating composition. In a preferred embodiment, colloidal silica is utilized. Also disclosed is a carbonless paper construction with at least a portion of at least one outer surface having the inventive pad-coat or release coating applied thereto. The incorporation of inorganic colloidal particles into carbonless paper pad-coats results in an increase in the coefficient of friction of the pad coated surface; increase in toner adhesion and ink receptivity of the pad-coated surface; promotes uniform feeding of carbonless paper sheets into photocopiers and printing presses by reducing misfeeds and double feeds; and reduces feeder induced smudging. It does this without loss of the abhesive release effect provided by the pad-coat and without loss of the fan-out ability to produce form-sets.

Abstract: A flooring system with internal cavities includes a shaped intermediate flooringlayer which is positioned between an upper flooring layer and a lower flooring layer and includes pot-shaped depressions and flat, intervening portions surrounding the depressions. The depressions are filled with a sound dampening filler material. This preventsaccumulation of the cementous top layer material in the region of the depressions which significantly reduces the drying time of the cementous top layer and reliably prevents internal tension in the top layer. Filling the depressions with sound absorbing material significantly reduces the transmission of sound or footsteps from the top layer to the bottom layer.
